I find apostrophes to be a very difficult concept for my ESL students, because they simply don't exist in most of their native languages.
This lesson breaks apostrophes down into two simple steps: Contractions and Possessives, and includes an optional practice game. Also included is a list of common contractions found online for teachers to use as examples in the classroom.
This lesson uses the workshop model and has a checkbox for the teacher to circle which standards they are using in the lesson. While it lists ESL standards and was used in a classroom with ESL students, this lesson is appropriate for students of all abilities and all grade levels. And, as with all my lessons, I use questioning and conversation to make students as much a part of the learning as possible.
